that president obama asked for of 400, almost $485 billion in 2011, even with the cuts in the army that that would have involved, the army would have still been roughly 30 or 40,000 troops bigger than it was when i became secretary in december of 2006. because i increased the size of the army by 65,000 in 2007, and then gave them an additional temporary increels of 2000 in 2008, or in 2010, rather, increels of 200,000, so i worry we think the answer is always go to be high tech, because it is cleaner, it is -- it dictates a different kind of war than we fought in iraq and afghanistan and i hope those are the kind of wars, if we have to fight, that that is what we don't have to go through what we went through in iraq and afghanistan, but i remember .. one of my favorite quotes is from general joe still well, from world war two, who basically said how a war starts, it always ends in mud. >> rose: ground forces fighting each other. >> and so you just don't know .. and because you don't know, you need to preserve flexibility. >> rose: you can't occupy with machines, can you, from the air? >
